i copied the files to /private/var/root/Media/
then i installed 1.1.3 soft upgrade ..... installer downloaded the package and installed it.
iPod made a reboot, but after the reboot it stocks with a picture of the usb and the itunes logo.

i opened itunes and it said that itunes detected an ipod in maintenance mode. The only option i can choose is Restoring the iPod. I think something went wrong.
